Classes were interrupted Thursday morning at Mendocino Hall after the fire alarm went off, causing the building to be evacuated.

English professor Dan Melzer said the alarm went off at about 10:20 a.m., 10 minutes before his class was scheduled to start.

He said his classes were usually held in Calaveras Hall, but he had reserved a computer lab in Mendocino Hall for a special day.

Students were allowed to re-enter the building at 10:31 a.m. after campus police and the Sacramento Fire Department declared it to be a false alarm.

Campus police officer Kevin Woods said that there was no fire, but he didn’t know whether someone had pulled the fire alarm or not.

As students were going back to class the alarm again sounded and some students decided to give up on class for the day.

“If I go in there now and it goes off again, I’m gone,” said Marie A. Celestine, a graduating senior English student.

Her class was located on the fourth floor.

A similar event took place Nov. 12, 2003, when someone pulled the fire alarm on the fourth floor causing hundreds to evacuate the building.
